Abstract: Abstract of the Disclosure A composite structure is disclosed which comprises a combination of heat treatable cemented carbides and alloy steel.  The carbide phase in the cemented carbide is predominantly tungsten monocarbide, or solid solutions of tungsten monocarbide and molybdenum monocarbide, of stoichiometric composi-tion.  The binder in the cemented carbide is based on heat treatable low to medium alloy steel and contains less than 2.5 percent by weight vanadium and less than 8 percent by weight chromium.  A method for making the cemented carbide is also disclosed.  The composite structure is formed by integral casting in steel of the preformed cemented carbide.  The composite structure can be heat treated to the desired hardness and toughness properties.  The primary area of application of the composites of the invention are in digger teeth for earthmoving, in mining and ore-comminution tools, and in cutter heads for deep-well drilling.

Abstract: PATENT APPLICATION          For "DYNAMIC LINEARIZATION SYSTEM FOR A RADIATION GAUGE"                        By Joseph A. Panarello ABSTRACT OF THE DISCLOSURE          The disclosed linearization system and process converts a high resolution non-linear analog input signal, representative of the thickness of an object, into a high resolution linear analog output signal suitable for use in driving a variety of out-put devices.  The system requires only a small amount of memory for storing pre-calculated non-linear correction coefficients. Prior art linearization systems typically require large memory configurations and/or powerful computers to develop the output signal from the non-linear input.  The known systems do not take advantage of the high resolution inherent in the input signal. The disclosed system "channels" the input signal to separate circuit paths so that it may be used directly to; (1) locate an appropriate correction coefficient; (2) develop a correction term after an appropriate correction coefficient is located   ; and (3) develop a linearized signal having the same high resolution inherent in the input signal.  Finally, the disclosed system processes the linearized signal to compensate for the possible errors introduced by radiation source noise.  The processed linearized signal is the high resolution linear analog output signal which accurately represents the thickness of the object being gauged.

Abstract: ABSTRACT OF THE DISCLOSURE A manually operable tube flaring tool for providing a partial flare in the end of a deformable tube.  The tool includes a flaring head defining an annular flaring surface and a cylindrical pilot portion projecting axially from the flaring surface to be received in the tube end for guiding the flaring surface axially against the distal end of the tube during the flaring operation.  The tool further includes a support for fixedly positioning the tube end coaxially ad-jacent the flaring operation of the flaring head.  The support defines an improved recess configuration providing a controlled buckling of the tube end by the forceful engagement therewith of the flaring surface wherein the buckled tube end defines preselected frustoconical inner and outer portions. The sup-port may further define a conventional single flare recess opposite the partial flare recess whereby the tube may be used selectively to provide either of the partial or single flare flaring operations. The tube clamp may be defined by one leg of the U-shaped body and a cooperating clamp block movably carried by the body and adjustably positioned by a threaded member threaded through the other leg of the body.

Abstract: AUTOMATIC MICROFILM CAMERA OPERATED      RESPONSIVE TO DATA INPUT AT A COMPUTER TERMINAL                     Abstract of Disclosure An automatic microfilm camera is positioned to take images of a document while it is being read by an operator of a computer terminal.  The computer generates a computer index number, and perhaps other significant information, which is forwarded via an interface circuit to display a readout of alpha-numerical images within the photographic area adjacent to the copied document.  The camera automatically takes a picture of the document and the display when the operator pushes an "Enter" or other appropriate button on the computer terminal, thereby photocopying both the document and the displayed images.  An important aspect of the invention is that the photographic cycle is initiated automatically by an appropriate step in the data entry sequence, whereby the normal data entry procedures are not disturbed by the existance or the use of the camera.  An advantage is that the camera and computer are inherently sychronized and cannot lose their mutual sequencing.

Abstract: ABSTRACT This invention relates to a screen device for separating undesir-able impurities from a pulp suspension.  The screen device is provided with at least one continuous circular screen slot provided between a first chamber into which unfiltered suspension is conducted through an inject-inlet and from which undesirable material is passed away through a reject-outlet.  There is a second chamber, from which screened pulp suspension is transported through an accept-outlet.  According to the invention the screen slot is formed by two walls which are stationary in relation to each other and a cleaning device in the form of a doctor or knife bears against the screen slot, said device and slot being movable in relation to each other for continuous cleaning of the screen slot,  Owing to this particles jammed in the screen slot are removed very effectively.  The rotation of the cleaning device or those walls forming the slot for most pulp suspensions may be made rather slow and therefore a screen of this type will not require great power.

Abstract: "ABSTRACT OF THE DISCLOSURE"           A process for the removal of H2S from a feed gas, and the production of sulfur therefrom, is effected by oxidation with oxygen at temperatures between 250° and 450°F.  The oxidation is conducted in the presence of an extremely stable oxidation catalyst comprising an oxide and/or sulfide of vanadium supported on a non-alkaline porous refractory oxide.  Sulfur deposition and consequent catalyst deactivation are prevented by maintaining the partial pressure of free sulfur in the oxi-dation reactor below that necessary for condensation.  H2, CO, and light hydrocarbons present in the feed gas are not oxidized.          Typical uses of the process include the removal of H2S and the production of sulfur from sour natural gases or gases obtained from the gasification of coal.         Feed gases which contain SO2 and H2S in mole ratios greater than 0.5, or which contain other gaseous sulfur com-pounds such as COS, CS2, SO3 and mercaptans, are desulfurized by catalytically converting all such sulfur components to H2S and subsequently removing the H2S from the product gas by catalytic oxidation to elemental sulfur.  This two-step catalytic process is especially contemplated for the desul-iurization of Claus tail gases.
